This post
is to inform you that I published recently a recent refcard on Java Performance
Optimization which is now available from DZone.
Refcardz are basically “Cheat Sheets” which can be very useful for Developers
and Application Support individuals.

“It is possible to define “optimal
performance” in different ways, but the basic elements are: the ability of a
Java program to perform its computing tasks within the business response time
requirements, and the ability of an application to fulfill its business
functions under high volume, in a timely manner, with high reliability and low
latency. Sometimes the numbers themselves become patternized: for some major
websites, a page response time of 500ms maximum per user function is considered
optimal. This Refcard will include target numbers when appropriate, but in most
cases you will need to decide these on your own, based on business requirements
and existing performance benchmarks…”
